Integral equation analysis of radiating structures of revolution

A methods for solving radiation problems involving structures of revolution is presented that is based on the direct solutions of one-dimensional integral equations for the currents. The kernels of these equations are derived explicitly and their singularities are studied. Efficient methods for their computation are presented. The numerical solution is obtained by a method of moments technique using sinusoidal basis functions. Applications include the determination of the current densities, reflection coefficient, and far-field patterns for several waveguide-fed structures. Numerical checks and comparisons with experiment demonstrate the accuracy of the method.<
